SKID-CH'AN FASTEN Application filed June 24,

To all whom 'it maf] concern-f f -Be it known that l, Josnrri rriiiniv, a

citizen of the UnitedStates,.residing at i va Y specification. Y

VThis inventionrelates to chain fasteners, and more particularlyto 'devices of this charao'terffor Vsecuring anti-skid chains upon wheels ofniotorgvehicles.y v

The object'ofthe invention is the provision of a fastener for the end 'links of. a chain which `will be positively but yieldabvly heldin closed position to eliminate the anh noyance due to the accidental separation of *theV chain endsand which vcan only be opened by force exerted onv the endv thereof.

Another objectris tofprovide'a fastener.

of thisV character whichV issiinplery in :con struction and'operation and which may be used I in connection with, chains of ivarious types. f Y

Another object is to provide :a fastener" of this character having; cooperating Vmembers so constructed and arranged as to presentno obstruction or projection Ywhich -wouldloe capable of engagement' by lextraneousA objects and cause the separation of said meni-` bers. i

With Vthese and other obiects in-view, the invention consistsin certain novel features of construction as hereinafter showin de-A scribed andfclaiined.'

In the accompanying drawings: Y Figure l represents a side'elevation of a Ychain fastener constructed in accordance lsimilar parts, sections of an anti-skid chain for Avehicle tires are shown of which 1. and 2 are the opposed links to be connected. rlhe 1 link l is permanently connected with the fastener which constitutesthe inventionin a manner presentlyto bedescribed7 while link 2 is detachablyA connected therewith.'

192i., sensi No'. 480,028.

The fastener comprises a: body vmember 5 which is made `in the forniof a bar, prol vided atoneen'd lwith'a plurality oflonkgitudinally spaced, laterallyvextending hooks 6, the terminals of said hooks being' of less thickness Vthan thebody portion thereof and .provided at their junction with sai-d body portion'with a shoulder 7 for a purpose presently to'be described These hooks `(i` are inclined'rearwardly and provided at their Y bases with reoeivin'e' ooeninffs 8` for the loose lunie e-Of ai@ Ciminbiolbeseurea.

These hooks 6 are adapted for insertion through the links 2 in one of the chain endg and for thepurpose-ofholding;1 saidlink in ings'S. l

The f lock side walls 12A-thereof fare .of a` thickness 'correspondingto the seats or shoulders 7 Vor closure member 10 is madel channel shape in cross section, and: theY intatta J V7o 'Y position a p'ivoted lock member l0 is pro-- walls thereof will-be flush with thoseiokf theVv i accidentally opening the fastener.

member: lO are `increased in size and apen tured to receivev a pintle 9 which connects' said-member l'Owith the member 5. said, aperturfedears 13 straddling the rear end of V extendingl the body portion of the member 10 atv the frontend thereofv and curving it to form springhook has a'curved bill 14,1 Vequipped at itsfree end with an outturned' lip l5 which.` facilitates the closing' of 'the locking member andl also the opening thereof.'

The front face ofthe foremost hook 6 has al recess formed therein `below the shoulders 7 thereof and 'which is cutV out to forni a Y curved latch portion lG'for interlocking enlsagement with the bill '1l of the member 1Q, as is shown clearly in Fig., l; while the ope posed wall 17 thereof is made rectilinear and 1710 Y tally opened, considerable force exerted on Y Y theVli-pjl being; necessary to disconnect the 15 is designed to form an abutment for Va tool' to be inserted between itV and the lin 15 of saidbill 11, to forcibly ber 11fiom the oro'ectino nose or latch 16.. j L Y 1 ,The nose 16 of member .5 proJects iongif tudinally inthe path of the spring latch member or bill 11, so that when said member 10 is shut down into locking position, this bill will snap over and interloclringly en gage` with said Anose and hold the member 10 securely looked to the member and prevent all possibility of its being accidenbill 11 from the' nose 16. lt is of Course. un-

fderstood, that before thisinenibei 10 is snappedl into lookingposition, that the looseV link 2 of the chain is engaged with one ofV the hooks 6 and; disposed in the seat or relcess S at the base thereof, as is shown clearly iii-Fig' 1., Y v

To release the Vmember 1:0 frointhe inem-v `be: 5, asorew driver or other implement is inserted between the lin and the abutment formed'by the shoulder 17 and a twist given to Ythe screwdriver which 'viill operate to ing noseV 1 6 of the fastener, ally possibility of the member 10 being accidentally disenfrono the cooperatingV member 5` is prevent-amend the lip 15 of' saidfbill lying` -vvithin the recess is Yprotected` against the engagement therewith of extraneous objects,

Vthe shoulder ,17 forming a guard therefor.

The link 1 is preferably made substan-Y Y tially Uashaped in formand the 'legs thereof are `providedY with eyes which` are engaged withV the fpintle 9.- at opposite sides, of the fastener as shown clearly inlvigs. 1 :and 2,

diseno'aoe said mem'- the fastener beingrthereby permanent ried by the chain. v Y i' A f The preferred embodiment ofA theinvention is disclosedY in the drmvings .and set forth in thespecificatiombnt it Will be liinderstoodV that any modifications Within the vscope of the kclaimed invention may bemade -in the construction Without departing from their-priifioipleY of the invention or? sacrificing any of its advantages.
